• Minimum 3 lesions enrollment.
• Injectable disease (i.e., suitable for direct intratumoral injection based on the dose level volume of each cohort and cumulative lesion size; according to the investigator's judgement).
• A lesion amenable for additional tumor biopsy.
• Patients with measurable disease according to the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria.

• Prior splenectomy.
• New and progressive brain lesions.
• Poor bone marrow reserve resulting in low blood cell count.
• Poor liver and kidney functions, abnormal coagulation tests.
• Ongoing or recent (within 5 years) evidence of significant autoimmune disease that required treatment with systemic immunosuppressive treatments.
• Maintenance therapy with prednisolone >7.5 mg/day orally or equivalent during the study.
